With its neo-retro styling, this exhaust features black-coated double conical mufflers constructed from high-grade stainless steel with a lightweight titanium link pipe. The design and lines of the exhaust have been specially developed to integrate with the bike, and the system is finished with a sandblasted stainless-steel heatshield to protect the riders equipment and a laser engraved Akrapovi logo on the muffler for a classy and refined look. During the development phase, the engineers focused on throttle response and rideability, with performance enhanced by a 0.9 kW (1.2 hp) increase in power and a torque gain of 1.6 Nm, both at 6,200 rpm, when compared to a BMW R 12 nineT equipped with a standard stock system and tested on the in-house dyno. Weight is reduced by 10.6% over the stock exhaust, and the Slip-On Line (SS) delivers a deep and sporty sound, which meets type approval for an EC/ECE certificate. This exhaust is a plug-and-play installation that requires no remapping. The exhaust system also fits on the BMW R 12 standard version.

Optional headers for BMW R12 nine T / R 12 will be available soon.
